THE C1
The 539g heavy heatsink of the C1 features a nice white shroud at the top and measures 144.5mm in length, 140mm in width and 61mm in height.
CRYORIG has printed their logo at the front of the shroud.
The main heatsink is made out of 56 aluminum fins 0.4mm thick each and spaced 1.8mm from each other (the two large holes are used to mount the cooler using the bundled screwdriver).
A second heatsink is located right beneath the primary one. This heatsink is made out of 35 aluminum fins 0.4mm thick each and spaced 1.4mm from each other.
Six nickel plated all-copper heatpipes leave the base of the C1 from both sides (six leave from the rear and 4 of them from the front) and pass through all of the 91 aluminum fins.
The nickel plated copper base doesn't feature a mirror-like finish but it's flat and well made.
Using a 13mm thick fan is not the best solution possible since the smaller blades produce less airflow (and static pressure) compared to larger ones. However with a maximum rotational speed of 1300RPM (+-10%) at 24dBA of noise and 65CFM of airflow the XT140 is actually not bad at all.
With the fan mounted on the heatsink the C1 is 74mm tall and weighs 628g.
